When I was younger I didn't know what spider lilies were, they were  a complete mystery to me. I now know and I would like to share what I have learned. ''Spider Lilies'' Spider Lilies are fall flowering bulbs which are about 3 inches long from top to bottom and 1 inch Wide. They pop up every were from along the road to peoples yard plus they multiply like crazy! I'll see  15 or 20 all bunched together. I have a few in a pot, that are just starting to come up and I just can't wait until they bloom. They stand 1-1 1/2 feet tall, and are a deep red.  They like organically rich well drained soil.
